Restoration of the Ellipsoid Zone and Visual Prognosis at 1 Year after Surgical Macular Hole Closure

Purpose. to evaluate the restoration of the ellipsoid zone (ez) and its influence on visual prognosis 1 year after surgical macular hole (mh) closure. method. subjects were patients with stage 2,3,or 4 idiopathic mh who underwent primary vitrectomy that resulted in successful hole closure. nineteen eyes with both ez disruption with foveal detachment and a continuous external limiting membrane on optical coherence tomography during the early postoperative period were included in this study. result. ez disruption was restored in 10 eyes (53%,group a) and remained in 9 eyes (47%,group b) at 1 year after surgery. in group b,the diameter of the residual ez disruption was 54.7 ± 33.1 μm. logmar visual acuity (va) 1 year after surgery was significantly better than preoperative va in each group (group a: - 0.007 ± 0.102; p < 0.001; group b: 0.051 ± 0.148; p < 0.001),but there was no significant difference between the 2 groups (p = 0.332). there was no significant correlation between logmar va and ez disruption diameter at 1 year after surgery. conclusion. ez was restored in 53% of eyes at 1 year after surgical closure of idiopathic mh. mean residual ez disruption diameter was 54.7 ± 33.1 μm. neither resolved nor residual ez disruption influenced postoperative va. copyright © 2016 hiruma hasebe et al.
